- Precise Fit: Designed specifically for 21700 batteries.
- Multiple Versions: Choose between 1, 2, 3, and 4 slots.
- Leave An Order Note: These are based on standard 21mm x 70mm batteries. ENSURE YOU MEASURE YOUR BATTERIES BEFORE ORDERING AND INCLUDE AN ORDER NOTE WITH THE DIMENSIONS, EVEN IF THEY ARE EXACTLY 21 x 70mm. Companies such as Fenix and Beston batteries like to make up their own dimensions for their batteries which may cause fit issues if you don't measure your batteries and leave this order note.
- Be Prepared: Carry spares for your flashlight or other device so you don't unexpectedly run out while shooting or otherwise out and about.
- Other Options: Cases for other batteries are also available! No batteries included.
- Original, Innovative Design: 2200+ products designed and 3D printed in the heart of America in St Louis, Missouri by Hammy3DPrints.
MATERIAL: 3D printed using PLA+ filament. Note that this filament is not a high-temp filament rated for use inside vehicles left in direct sunlight during summer. If you require a higher-temp filament please contact me.
INSTALLATION: Lids slides on and off by hand. For the single slot version, the cap twists on and off.
WARRANTY: If this item breaks I will make any design adjustments, if needed, and send a replacement for free.
Made in USA.
Please note that the products may have slight imperfections as 3D Printing is rarely perfect. The exact product you receive may also slightly vary from the product photos as I iterate and improve upon designs based on user feedback.

Another outstanding product from Hammy. The case fits nitecore and modlite 21700 5000mah batteries. The nitecore one slips in, but the modlite ones are half a hair larger than the nitecore so they require a very light push into the slot, and a couple jerking motions taps on the hand to get out. Otherwise absolutely amazing product. Regardless of my statement follow the instructions and send the measurements in with your order so Hammy can tell you if it’ll work or not.
Absolutely awesome! I messed up the dimensions on my batteries initially but Hammy was super accommodating. Outstanding customer service and excellent quality product. Fits my oversized 21700s like a glove. Thank you!
Great custom print. The seller was attentive enough to check which batteries I was trying to store and ensured the print was exactly to those dimensions. Will order again.
The item is well made as advertised, the battery slots perfectly fits my fenix 21700 batteries, no wobbling, no rattling noise during transport. The cover seems to function well, it would be nice if it has some sort of a notch to ease the release of the locking mechanism. All in all its a great product and im happy with my purchase.
Vendor contacted me for brand/dimensions which were easy to find, attention to detail, how refreshing! Will use this vendor again!
As described, very happy with it. Batteries fit perfectly.
The battery case sold here looks great and feels super sturdy. Battery manufacturers are the worst when it comes to adhering global specifications, but Hammy3DPrints is absolutely awesome about making sure to custom fit it. When you send the proper specs, the case fits like a glove!

Great product. Batteries fit perfectly! The seller sent a message to clarify the dimensions of the specific battery I was using, which was really nice because Olight batteries are larger than the standard dimensions for 21700 batteries. So nice to have spare batteries all in one place. Fit, finish, and colors are nice for what you'd expect for 3D printing. The lid slides freely and fits great. Definitely would recommend.
Excellent quality and exceptional customer service, highly recommended!
